+# Testing Pipe-Delimited Usecase Filtering in Cloud Run
+
+## Overview
+
+This document provides testing instructions for the pipe-delimited usecase filtering functionality in Logstory's Cloud Run deployment. This feature allows you to filter which usecases are processed when using `replay all` by setting the `LOGSTORY_USECASES` environment variable.
+
+## Feature Description
+
+The `LOGSTORY_USECASES` environment variable filtering feature allows you to:
+
+- Use `replay all` command with selective usecase processing
+- Avoid gcloud argument parsing issues entirely
+- Filter usecases using pipe-separated values (e.g., `NETWORK_ANALYSIS|GITHUB`)
+- Maintain backward compatibility - no filtering variable means process all usecases
+
+## Implementation
+
+When `LOGSTORY_USECASES` is set, the `replay all` command:
+1. Parses the pipe-separated usecase list
+2. Validates that all requested usecases exist
+3. Only processes the specified usecases instead of all available ones
+4. Provides clear feedback about which usecases are being processed
+
+## Local Testing
+
+### Prerequisites
+
+Set up your development environment:
+
+```bash
+# Create and activate virtual environment
+python -m venv venv
+source venv/bin/activate
+
+# Install in editable mode
+pip install -e .
+
+# Set required environment variables
+export LOGSTORY_CUSTOMER_ID=your-uuid
+export LOGSTORY_CREDENTIALS_PATH=/path/to/credentials.json
+export LOGSTORY_REGION=US
+export LOGSTORY_API_TYPE=rest
+```
+
+### Test Cases
+
+#### 1. Test Normal Behavior (No Filtering)
+
+```bash
+# Should process all available usecases
+logstory replay all --local-file-output
+
+# Expected output: "Processing all usecases: NETWORK_ANALYSIS, RULES_SEARCH_WORKSHOP, ..."
+```
+
+#### 2. Test Single Usecase Filtering
+
+```bash
+# Filter to single usecase
+LOGSTORY_USECASES=NETWORK_ANALYSIS logstory replay all --local-file-output
+
+# Expected output: "Processing filtered usecases: NETWORK_ANALYSIS"
+```
+
+#### 3. Test Multiple Usecase Filtering
+
+```bash
+# Filter to multiple usecases
+LOGSTORY_USECASES=NETWORK_ANALYSIS\|RULES_SEARCH_WORKSHOP logstory replay all --local-file-output
+
+# Expected output: "Processing filtered usecases: NETWORK_ANALYSIS, RULES_SEARCH_WORKSHOP"
+```
+
+#### 4. Test Error Handling
+
+```bash
+# Test with invalid usecase
+LOGSTORY_USECASES=INVALID_USECASE logstory replay all --local-file-output
+
+# Expected: Error message listing available usecases
+```
+
+## Cloud Run Testing
+
+### Prerequisites
+
+Ensure your Cloud Run environment is set up:
+
+```bash
+# Set required environment variables
+export LOGSTORY_API_TYPE=rest
+export LOGSTORY_CUSTOMER_ID=your-uuid
+export LOGSTORY_PROJECT_ID=your-project-id
+export LOGSTORY_REGION=US
+
+# Build and deploy updated Docker image
+make build
+make docker-build
+```
+
+### Test Cases
+
+#### 1. Test Normal Cloud Run Behavior
+
+```bash
+# Process all usecases (no filtering)
+gcloud run jobs execute logstory-replay \
+  --region us-central1 \
+  --args "logstory,replay,all" \
+  --wait
+```
+
+#### 2. Test Single Usecase Filtering
+
+```bash
+# Filter to single usecase
+gcloud run jobs execute logstory-replay \
+  --region us-central1 \
+  --args "logstory,replay,all" \
+  --update-env-vars "LOGSTORY_USECASES=NETWORK_ANALYSIS" \
+  --wait
+```
+
+#### 3. Test Multiple Usecase Filtering
+
+```bash
+# Filter to multiple usecases using pipe separator
+gcloud run jobs execute logstory-replay \
+  --region us-central1 \
+  --args "logstory,replay,all" \
+  --update-env-vars "LOGSTORY_USECASES=NETWORK_ANALYSIS|RULES_SEARCH_WORKSHOP" \
+  --wait
+```
+
+#### 4. Test with Additional Options
+
+```bash
+# Combine filtering with entities and custom timestamp delta
+gcloud run jobs execute logstory-replay \
+  --region us-central1 \
+  --args "logstory,replay,all,--entities" \
+  --update-env-vars "LOGSTORY_USECASES=NETWORK_ANALYSIS,LOGSTORY_TIMESTAMP_DELTA=3d" \
+  --wait
+```
+
+## Validation Methods
+
+### Check Execution Status
+
+```bash
+# Get the latest execution name
+EXECUTION_NAME=$(gcloud run jobs executions list \
+  --job logstory-replay \
+  --region us-central1 \
+  --limit 1 \
+  --format "value(name)")
+
+# Check if it completed successfully
+gcloud run jobs executions describe $EXECUTION_NAME \
+  --region us-central1 \
+  --format "value(status.conditions[0].status)"
+```
+
+### Analyze Logs
+
+```bash
+# Install beta components if needed
+gcloud components install beta --quiet
+
+# View execution logs
+gcloud beta run jobs executions logs read $EXECUTION_NAME --region us-central1
+```
+
+### Success Indicators
+
+Look for these patterns in the logs:
+
+**Filtered Processing:**
+```
+Processing filtered usecases: NETWORK_ANALYSIS, RULES_SEARCH_WORKSHOP
+Processing usecase: NETWORK_ANALYSIS, logtype: BRO_JSON
+Processing usecase: RULES_SEARCH_WORKSHOP, logtype: POWERSHELL
+Successfully posted entries using RestIngestionBackend
+```
+
+**Normal Processing:**
+```
+Processing all usecases: NETWORK_ANALYSIS, RULES_SEARCH_WORKSHOP, THW2
+```
+
+**Error Handling:**
+```
+Error: Invalid usecases: INVALID_NAME
+Available usecases: NETWORK_ANALYSIS, RULES_SEARCH_WORKSHOP, THW2
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Issue: Container Exits with Error
+**Solution:** Check execution logs for specific error messages and verify environment variables are set correctly.
+
+#### Issue: All Usecases Processed Despite Filtering
+**Solution:** Verify the Docker image was rebuilt and deployed after code changes. Check that `LOGSTORY_USECASES` environment variable is correctly set.
+
+#### Issue: Invalid Usecase Error
+**Solution:** Run `logstory usecases list-installed` to see available usecases, or check the error message for the list of valid options.
+
+### Debugging Commands
+
+```bash
+# Check job configuration
+gcloud run jobs describe logstory-replay --region us-central1
+
+# List recent executions
+gcloud run jobs executions list \
+  --job logstory-replay \
+  --region us-central1 \
+  --limit 5
+
+# Check environment variables in job
+gcloud run jobs describe logstory-replay \
+  --region us-central1 \
+  --format "value(spec.template.template.spec.template.spec.containers[0].env[])"
+```
+
+## Benefits
+
+1. **No gcloud parsing issues** - Environment variables avoid command-line argument parsing problems
+2. **Clean command structure** - Simple `logstory,replay,all` arguments
+3. **Flexible filtering** - Easy to specify any combination of usecases
+4. **Backward compatible** - Existing behavior preserved when no filtering is specified
+5. **Clear feedback** - Logs clearly show which usecases are being processed
+
+## Usage Examples
+
+### Development Workflow
+
+```bash
+# Test locally first
+LOGSTORY_USECASES=NETWORK_ANALYSIS|RULES_SEARCH_WORKSHOP logstory replay all --local-file-output
+
+# Deploy to Cloud Run
+make build && make docker-build
+
+# Test in Cloud Run
+gcloud run jobs execute logstory-replay \
+  --region us-central1 \
+  --args "logstory,replay,all" \
+  --update-env-vars "LOGSTORY_USECASES=NETWORK_ANALYSIS|RULES_SEARCH_WORKSHOP" \
+  --wait
+```
+
+### Production Usage
+
+```bash
+# Set environment variables in .env file or Cloud Run job configuration
+LOGSTORY_USECASES=PRODUCTION_USECASE_1|PRODUCTION_USECASE_2
+
+# Deploy with scheduled execution
+gcloud run jobs execute logstory-replay \
+  --region us-central1 \
+  --args "logstory,replay,all" \
+  --wait
+```
+
+This implementation provides a clean, reliable solution for filtering usecases in Cloud Run deployments while maintaining full backward compatibility and avoiding all gcloud argument parsing issues.
